These include mnc, mnc, and different variations of operator name. Additionally, in case NET_OPER_NAME_READ_RESP is an error result, which happens with some operators, report the extracted information to core instead of bailing out. --- drivers/isimodem/debug.c | 1 + drivers/isimodem/network-registration.c | 73 ++++++++++++++++++++++++- drivers/isimodem/network.h | 1 + 3 files changed, 74 insertions(+), 1 deletion(-) diff --git a/drivers/isimodem/debug.c b/drivers/isimodem/debug.c index 18055791..8edcd972 100644 --- a/drivers/isimodem/debug.c +++ b/drivers/isimodem/debug.c @@ -1190,6 +1190,7 @@ const char *net_subblock_name(enum net_subblock value) _(NET_REGISTRATION_CONF1_INFO); _(NET_ROAMING_CONF1_INFO); _(NET_AVAIL_NETWORK_INFO_COMMON); + _(NET_REG_STATUS_IND_OPER_NAME); _(NET_OPER_NAME_INFO); } return "NET_"; diff --git a/drivers/isimodem/network-registration.c b/drivers/isimodem/network-registration.c index 8f70b3ee..bdfb8fd0 100644 --- a/drivers/isimodem/network-registration.c +++ b/drivers/isimodem/network-registration.c @@ -80,6 +80,8 @@ struct netreg_data { struct rat_info rat; GIsiVersion version; char nitz_name[OFONO_MAX_OPERATOR_NAME_LENGTH + 1]; + char mcc[OFONO_MAX_MCC_LENGTH + 1]; + char mnc[OFONO_MAX_MNC_LENGTH + 1]; }; static inline guint8 *mccmnc_to_bcd(const char *mcc, const char *mnc, @@ -193,6 +195,12 @@ static void reg_status_ind_cb(const GIsiMessage *msg, void *data) struct netreg_data *nd = ofono_netreg_get_data(netreg); GIsiSubBlockIter iter; + uint8_t len = 0; + uint8_t type = 0; + char *abbrev = NULL; + char *an = NULL; + char *fn = NULL; + if (netreg == NULL || nd == NULL) return; @@ -209,16 +217,69 @@ static void reg_status_ind_cb(const GIsiMessage *msg, void *data) if (!parse_common_info(&iter, &nd->reg)) return; + + /* Parse abbreviated operator name */ + if (!g_isi_sb_iter_get_byte(&iter, &len, 7)) + return; + + len *= 2; + + if (!g_isi_sb_iter_get_alpha_tag(&iter, &abbrev, len, 8)) + return; break; case NET_GSM_REG_INFO: if (!parse_gsm_info(&iter, &nd->gsm)) return; + + /* Parse mcc and mnc */ + if (!g_isi_sb_iter_get_oper_code(&iter, nd->mcc, + nd->mnc, 8)) + return; + break; + + case NET_REG_STATUS_IND_OPER_NAME: + + if (!g_isi_sb_iter_get_byte(&iter, &type, 2)) + return; + + if (!g_isi_sb_iter_get_byte(&iter, &len, 5)) + return; + + /* Name is UCS-2 encoded */ + len *= 2; + + switch (type) { + case 2: + /* + * Alternate full name, which is similar to + * long name, but may have less whitespace + */ + g_isi_sb_iter_get_alpha_tag(&iter, &an, len, 6); + break; + case 3: + /* Full name */ + g_isi_sb_iter_get_alpha_tag(&iter, &fn, len, 6); + break; + } break; } } + if (fn[0] != '\0') + strncpy(nd->nitz_name, fn, OFONO_MAX_OPERATOR_NAME_LENGTH); + else if (an[0] != '\0') + strncpy(nd->nitz_name, an, OFONO_MAX_OPERATOR_NAME_LENGTH); + else if (abbrev[0] != '\0') + strncpy(nd->nitz_name, abbrev, OFONO_MAX_OPERATOR_NAME_LENGTH); + + nd->nitz_name[OFONO_MAX_OPERATOR_NAME_LENGTH] = '\0'; + + g_free(an); + g_free(fn); + g_free(abbrev); + ofono_netreg_status_notify(netreg, isi_status_to_at_status(&nd->reg), nd->gsm.lac, nd->gsm.ci, isi_to_at_tech(&nd->rat, &nd->gsm)); @@ -458,6 +519,8 @@ static void name_get_resp_cb(const GIsiMessage *msg, void *data) { struct isi_cb_data *cbd = data; ofono_netreg_operator_cb_t cb = cbd->cb; + struct ofono_netreg *netreg = cbd->user; + struct netreg_data *nd = ofono_netreg_get_data(netreg); struct ofono_network_operator op; GIsiSubBlockIter iter; @@ -468,7 +531,14 @@ static void name_get_resp_cb(const GIsiMessage *msg, void *data) if (!check_response_status(msg, NET_OLD_OPER_NAME_READ_RESP) && !check_response_status(msg, NET_OPER_NAME_READ_RESP)) - goto error; + if (nd->nitz_name[0] == '\0') + goto error; + + strncpy(op.name, nd->nitz_name, OFONO_MAX_OPERATOR_NAME_LENGTH); + op.name[OFONO_MAX_OPERATOR_NAME_LENGTH] = '\0'; + strncpy(op.mcc, nd->mcc, OFONO_MAX_MCC_LENGTH); + strncpy(op.mnc, nd->mnc, OFONO_MAX_MNC_LENGTH); + goto success; for (g_isi_sb_iter_init(&iter, msg, 6); g_isi_sb_iter_is_valid(&iter); @@ -500,6 +570,7 @@ static void name_get_resp_cb(const GIsiMessage *msg, void *data) } } +success: CALLBACK_WITH_SUCCESS(cb, &op, cbd->data); return; diff --git a/drivers/isimodem/network.h b/drivers/isimodem/network.h index 7449a1d0..3282b383 100644 --- a/drivers/isimodem/network.h +++ b/drivers/isimodem/network.h @@ -90,6 +90,7 @@ enum net_subblock { NET_REGISTRATION_CONF1_INFO = 0x59, NET_ROAMING_CONF1_INFO = 0x5A, NET_AVAIL_NETWORK_INFO_COMMON = 0xE1, + NET_REG_STATUS_IND_OPER_NAME = 0xE3, NET_OPER_NAME_INFO = 0xE7, };
